Title (EN) OFFSET COMPENSATING CIRCUIT
(FR) CIRCUIT DE COMPENSATION DECALEE
Abstract: front page image
(EN)Offset compensating circuit adapted to be built into a circuit to be compensated. The offset compensating circuit (21) is incorporated into a negative feedback loop of the circuit to be compensated, and essentially comprises an integrating circuit. The integrating circuit is composed of switching means (SW) and a switched capacitor-type integrating circuit (23). The switching means (SW) operates to feed either one of a positive reference voltage (+ Vr) and a negative reference voltage (- Vr) in response to the polarity of the output signal from the circuit to be compensated. The positive or negative reference voltage (+ Vr) is applied to the switched capacitor-type integrating circuit (23), which generates an offset compensating voltage (Vc) to be superposed to the input signal of the circuit to be compensated.
(FR)Un circuit de compensation decalee est adapte pour etre monte dans un circuit a compenser. Le circuit de compensation decalee (21) est incorpore dans une boucle de reaction negative du circuit a compenser, et comprend essentiellement un circuit d"integration. Le circuit d"integration se compose de moyens de commutation (SW) et un circuit d"integration du type a condensateur branche (23). Les moyens de commutation (SW) alimentent l"une ou l"autre des tensions de reference positive (+Vr) et negative (-Vr) en reponse a la polarite du signal de sortie provenant des circuits a compenser. La tension de reference positive ou negative (+Vr) est appliquee au circuit d"integration du type a condensateur branche (23), qui produit une tension de compensation decalee (Vc) pour etre superposee sur le signal d"entree du circuit a compenser.
